Durlock Bolts

Controlled hexagon for maximum wrenching strength. Controlled serrated Flange for better gripping with mating part. Smooth fillet radius to withstand head soundness. Formed threads with improved root radius provide greater strength to threads. Uniform & uninterrupted grain flow for greater strength. Controlled mechanical properties for higher strength. High grade alloy steel for good strength & wear resistance. Controlled Concentricity in totality helps to create a high resistance to lateral movements.
